LAURITZ-W. ANDERSEN, OFWUA'ITERIBUlt'tY CONNECTICUT;

DETACHABLE COLLAR FOB, SHADES.

Application filed February This invention relates generally to shade holders for electric light fixtures and more particularly to a collar capable of attachment to a glass, fabric, paper or metallic shade for the purpose of providing a suitable means of attachment or connection between the socket cover and the shade of the lamp or fixture.

At the present time glass shades are usually formed with a lip against which the thumb screw of the socket cover bears for the purpose of connecting the shade to the socket cover.

By means of my invention this lip is not necessary inasmuch as the collar which I have designed is attachable to the glass shade and takes the place of the same. The same thing is true with reference to fabric and parchment shades. My invention may, therefore, be broadly described as a collar attachable to the upper end of a shade and having prongs or fingers for connecting the collar to the upper end of the shade, said collar serving as a bearing point for the thumb screw carried by the socket cover, the incandescent bulb having its terminal end passed through the collar into the socket, this socket in turn being arranged within a cover Or spider which provides the support for the shade.

The invention consists also in certain details of construction all of which will be more fully described hereinafter and set forth in the appended claims.

In the drawings forming a part of the specification, Fig. 1 is a perspective of my iiu'iproved construction of collar showing the application thereof, the socket cover and shade being indicated in dotted lines; Fig. 2 is a sectional view showing the socket cover, shade and collar together with the socket arranged in the cover, the bulb being indicated in dotted lines; Fig. 3 is a top, plan view of the collar attached to the top of the shade; and Fig. 4: is a sectional view showing the collar attached to the top of a fabric shade.

In the practical embodiment of my invention I employ a sheet metal collar A circular in form and having the downwardly extending flange A and the horizontal inwardly extending annular flange A said annularflange A having a series of radial inwardly extending tongues or lingers B. C indicates a glass shade which 18, 1925; Serial No. 9,930[

is devoid of 'th'e usual lip at the upper end thereof.

in practice, my improved collar is arranged upon the shade C, the flange A coutacting with the exterior thereof, and the integral tongues or fingers B are bent around the edges of the opening in the top of the shade thereby securely connecting the collar to the shade and providing a lip against which the set screw D carried by the socket cover E can be made to bear for the purpose of completing the connection between the shade and socket cover. F indicates the standard type of socket arranged within the cover E and G is the usual construction of incandescent bulb which has its terminal screwed into the socket F. i

In Fig. & I have shown a fabric or parchment shade G connected to a wire frame H and in construction such as this the tongues or fingers B are bent around the upper ring member H of the frame, the flange portion A of the collar resting upon the upper end of the shade in exactly the same manner as upon the glass shade. The connection between the socket cover is also made in exactly the same manner, that is by means of the set screws D.

My improved collar supplies the attaching lip connection and consequently it will not be necessary to manufacture shades with said lip and furthermore it will be seen that my improved construction of collar is interchangeable with all kinds of shades, such as glass, parclnnent, fabric and the like. The tongues or fingers are readily bendable into engagement with the upper end of the shade and when once positioned will remain.

The insertion, however, of the bulb into the socket renders disengagement impossible as it will be seen that the bulb contacting or approximately contacting with these tongues or fingers will prevent any unbending or unfolding thereof such as would permit the separation of the parts.

, It will thus be seen that I provide an exceedingly simple and efficient device capable of performing all of the various functions hereinbefore recited.

Having thus described my invention, what I claim is:

1. As a new article of manufacture, a detachable collar for shades comprising a mil depending flange adapted to contact with the exterior of the shade, an inwardl extending flange and a plurality of radially inwardly projecting bendable fingers adapted to be bent into engagement with the inner side of the shade,

2. The combination with a socket and its cover, said cover having set screws extending through the end thereof, a shade and a 10 collar, said collar comprising a depending flange contacting with the exterior of the shade, an inwardly projecting flange and a plurality of integral inwardly extending bendable fingers contacting with the inner side of the shade, the set screws 01": the cover engaging the depending flange of the collar. In testimony whereof, I hereunto aflix my signature.
